Me or am i pregnant??? Plz help im stressing so much and panicing.

I had a short three day mini period after taking the pill like the 21-23 of nov then my regular period came dec 3-6. Is it still the pill??im usually due for my period the second or third of the month but now its three days late .what should i do?

If you are nervous about being pregnant take a test just to ease your mind! I know easier said then done but just try not to stress.I too am going through the same thing, I had my normal period dec20th, unprotected sex jan5th and took plan b jan 7th, when I was suppose to get my period I jus spotted only when I whipped, that lasted for a day or 2. Now I am 23 days late and still waiting for my next period, all pregnancy test are negative so far.
